Due primarily to the employment of its “near-net-shape” process, investment casting reduces waste when producing an endless array of parts. Because investment castings typically do not need much or any machining and finishing work, only a relatively small amount of material is wasted. This can be quite significant in long runs and when costly alloys are specified. Also, it is common to have fewer rejected parts with investment casting, because of its high quality, precision and repeatability. An added plus is the reduced waste supports a commitment to sustainability.
